What Is Google Maps? Features, Business Use and AI Navigation

What is Google Maps? It is a free web and mobile mapping service built by Google that lets people find locations, get turn-by-turn directions, check live traffic, explore places through satellite imagery and street-level photography, and discover local businesses. That definition has held since 2005. What sits behind it has changed almost beyond recognition.

Google Maps now handles navigation for billions of journeys, surfaces local businesses in “near me” searches, plugs into public transport networks across the UK and Ireland, and uses Gemini AI to answer questions posed in plain English rather than keywords. For a business in Belfast, Derry or anywhere across Northern Ireland, that shift matters commercially. Your Maps listing is often the first thing a customer sees, and increasingly it is the source an AI assistant draws on when someone asks for a recommendation. Getting it right is part of a wider digital strategy, not a box-ticking exercise.

This guide covers how the platform processes location data, which features earn their keep, what the UK and Irish integrations actually do, how businesses appear in local results, and which privacy settings matter under UK GDPR.

What Is Google Maps and How Did It Start?

The history explains the current dominance. Google bought Keyhole, a geospatial satellite imaging company, in 2004. Google Maps launched publicly the following year, pairing satellite imagery with street-level mapping at a scale nobody had attempted.

Expansion has been continuous since. Waze brought crowdsourced traffic reporting when Google acquired it in 2013. Street View grew through a global fleet of camera cars. Public transport timetables arrived operator by operator. Gemini AI now powers conversational search inside the app. ProfileTree’s guide to Google Maps marketing for local businesses covers the commercial side of that evolution in more depth.

From Navigation Tool to Real-Time Geospatial Platform

The most useful way to think about Google Maps today is as a live model of the physical world rather than a picture of it. Geography is the base layer. On top sit traffic flow, opening hours, reviews, air quality readings and environmental zone boundaries, all updating continuously.

For UK users that includes Ordnance Survey topographical data, live departure information from Transport for London and National Rail, and alerts when a route crosses London’s Ultra Low Emission Zone or a Clean Air Zone such as Birmingham’s. Google reported in 2020 that more than one billion kilometres are driven with Google Maps every day across more than 220 countries and territories. Businesses working across both jurisdictions on the island of Ireland will find the same platform behaves differently either side of the border, which is one reason local marketing in Ireland needs a jurisdiction-aware approach rather than a single template.

Google Maps does not run on one data source. It fuses several layers at once, and understanding which layer does what makes the platform far easier to use well.

GPS, Location Data and Anonymous Traffic Signals

When a device has Location Services switched on, it sends anonymised packets to Google containing coordinates and movement speed. When enough devices report slow progress along the same stretch of road, the traffic overlay updates. The accuracy is a function of adoption: more users produce better data.

Google also holds years of historical traffic patterns, which supports prediction as well as live reporting. Plan a Friday afternoon journey on the M25 and the estimate you see combines current conditions with what that road has done at that hour for years.

Satellite Imagery, Street View and 3D Reconstruction

Three imaging technologies work together. Satellite imagery provides the aerial base layer. Street View, captured by 360-degree camera cars, provides ground-level photography of streets and buildings. AI reconstruction techniques then interpolate between those images to produce the fluid three-dimensional Immersive View, which lets you drop into a location and look around before you travel.

The practical effect is that a tourist planning a trip to Edinburgh gets a walkable visual preview rather than a flat plan. You can follow a street, check a restaurant frontage, or judge the walk from a station to a hotel.

Google Maps and GPS: What Is the Difference?

These two get conflated constantly, and the distinction is simple. GPS is a satellite constellation and the hardware that reads it; it tells a device where on Earth it is, expressed as coordinates. Google Maps is the software layer that takes those coordinates and turns them into something usable: a rendered map, a route, an arrival estimate, a list of nearby businesses.

A phone with no signal still receives GPS coordinates. What it loses without a connection is the interpretation, which is why offline maps exist.

Without its feature set, Google Maps is a flat map. The features are the difference, and a handful of them do most of the practical work.

Navigation and Live Directions

Point-to-point navigation is the foundation. Enter a destination, pick a mode (driving, walking, cycling or public transport) and the platform calculates a route against live traffic. Voice directions let you keep your eyes on the road, which matters under UK law, where using a handheld device while driving carries a fixed penalty and points.

Street View

Street View is one of the more genuinely useful features for individuals and businesses alike. Customers use it to recognise a destination before arriving. Businesses benefit when their frontage is current, because outdated imagery of a shop that has since been refitted undercuts the impression a well-maintained listing creates.

Access on desktop is straightforward: search a location, then drag the yellow Pegman icon from the lower right onto a street. On Android and iOS, tap a location pin and select the Street View thumbnail. Arrows on screen move you along the street.

Offline Maps

Offline mode is regularly overlooked. Download a map area in advance and navigation keeps working without a data connection, which helps in rural Fermanagh or the Scottish Highlands as much as it does abroad when you would rather avoid roaming charges. Downloaded areas include roads and turn-by-turn directions. Live traffic and real-time transit data need a connection.

Live View and Augmented Reality

Live View uses the device camera to lay directional arrows over the real world on screen. Instead of interpreting a flat map while standing on a corner, you see arrows placed on the pavement ahead. It earns its place in dense city centres where street layouts are confusing and a compass reading is not much help.

Gemini AI and Conversational Search

Gemini’s arrival inside Google Maps changed how people search it. Where a query once had to be phrased as keywords (“Italian restaurant Shoreditch”), it can now be phrased as a request: “somewhere quiet to work with good coffee and reliable WiFi near Liverpool Street”. The platform reads reviews, attributes and photos to answer.

This is the same shift already visible in voice search behaviour, where queries are longer, more conversational and framed as questions. Both reward businesses whose listings contain enough real detail to answer a specific request. A profile that says only “cafe” cannot be matched to “quiet, gluten-free, good for laptops”. A profile with attributes, service details, photos and recent reviews can. There are AI tools that help manage a Business Profile at that level of detail, and ProfileTree’s work on AI in marketing covers how intent-based discovery is reshaping the same problem across other channels.

Custom Maps and Embedding

Most casual users never touch My Maps, which allows custom maps with markers, drawn shapes and labels. Businesses can embed an interactive map directly into a web page, and doing it properly matters more than it sounds: a badly implemented embed is one of the more common causes of poor mobile performance on location pages. ProfileTree’s web design team in Belfast handles this as standard when building location-based pages.

How Google Maps Serves the UK and Ireland

Global guides to Google Maps skip the regional detail, and for anyone travelling or trading in the UK and Ireland that detail is most of the value. Three integrations do the heavy lifting.

Public Transport: TfL, National Rail and Translink

Google Maps carries live departure data rather than static timetables across much of the UK network. In London that means Transport for London tube and bus departures. Nationally it means National Rail platform changes and delay information. In Northern Ireland it means Translink services, including Belfast’s Glider rapid transit routes, which is a meaningful difference for anyone planning a cross-city journey.

Clean Air Zones and Emission Alerts

Drivers in Britain now face a patchwork of charging zones, and Google Maps flags them during route planning. If a route crosses London’s ULEZ or a Clean Air Zone such as Birmingham’s, the app displays a warning and offers alternatives where a viable route exists. The alert is a prompt to check, not a charge calculator; liability still depends on your vehicle’s emissions rating.

For businesses across Northern Ireland, Ireland and the UK, this is where Google Maps stops being a utility and becomes a channel. It is the primary route by which local customers find nearby services, check hours, read reviews and get directions. A business set up incorrectly on Google Maps is invisible to a large share of the people actively looking for it.

Google Business Profile: Your Foundation

The Google Business Profile is the free listing that controls what searchers see: name, address, phone number, hours, website link, photos, categories and reviews. It is the single most valuable asset in local search, and it is also the one most often left half-finished.

The Profile’s own performance data is under-used too. ProfileTree’s breakdown of Google Business Profile performance data covers what the interaction and discovery reports actually tell you about how customers are finding you. Worth saying plainly: the listing supports your website rather than replacing it, and a properly built site is still where enquiries convert. Profile optimisation forms part of ProfileTree’s search engine optimisation work for businesses across the region.

“When we audit a local business’s digital presence, the Google Business Profile is almost always the fastest win available. Correcting the address, adding real photographs and replying to reviews are small jobs with a disproportionate effect. After that, the listing does the marketing around the clock.” Ciaran Connolly, founder of ProfileTree

Near Me Searches and the Local Pack

Search “web designer near me” or “accountant Belfast” and the results include a local pack: three prominently placed listings sitting above the organic results. Appearing there drives real traffic.

Google is unusually direct about how those positions are decided. Its Business Profile documentation names three factors: relevance, meaning how well the profile matches the search; distance, meaning how far the business is from the searcher or the location implied by the query; and prominence, meaning how well known the business is, judged partly on how many sites link to it and how many reviews it has. Distance is largely fixed. Relevance and prominence are the two you can work on.

Prominence is where citation consistency does its quiet work. Listings on reputable business directories reinforce your name, address and phone number across the web, and inconsistency between them is a common drag on local visibility.

How this plays out varies by sector. The competitive radius for a cafe is measured in minutes, which makes local search for restaurants and cafes a different discipline from the service-area problem facing trades businesses across Northern Ireland, where the question is which towns you can credibly claim to serve.

Google Maps Reviews and Reputation Management

Reviews are the most visible part of any Maps listing. Star rating and review count appear before a searcher has clicked anything, and they influence both click-through rate and the decision that follows. ProfileTree’s analysis of what review data shows for SMEs sets out how volume, recency and response rate interact.

A steady flow of recent reviews tends to outperform a larger pile of old ones. Replying to criticism as well as praise signals active management to Google and to the person reading. Review response also sits inside a broader content marketing approach, since the trust signals you build in one place get read in others.

Google Maps and AI Search Visibility

Here is the part most guides miss. When someone asks ChatGPT, Perplexity or Gemini to recommend a local business, the model draws on what is indexed about that business across the web, and Business Profile data is part of that picture. Your Maps listing is no longer only a Google asset; it feeds the answers other systems give.

That raises the value of accuracy considerably, because a wrong opening time repeated by three AI assistants is a harder problem than a wrong opening time on one page. Businesses running AI chatbots on their own site add a further layer, catching visitors who arrive from a Maps search wanting an immediate answer.

What does the app record about you while you use it? A fair question, and one with a clearer answer in the UK than in many jurisdictions, because UK GDPR gives individuals specific rights over their personal data.

Location History and the Timeline Feature

Timeline records where you have travelled when Location History is switched on for your Google account. That includes routes taken, places visited and time spent at each. All of it can be reviewed, edited or deleted, and Google offers auto-delete settings that clear location history after 3, 18 or 36 months.

Incognito Mode and UK GDPR Rights

Incognito Mode, reached through the account menu in the app, stops searches and navigation being saved to your account or used to personalise later recommendations.

Since Brexit the UK has operated under UK GDPR, which gives individuals the right to access, correct and delete their personal data, and to object to its processing. Google’s own controls sit at myaccount.google.com. Teams that want to understand how these obligations affect day-to-day marketing operations can look at ProfileTree’s digital training programmes, which cover data handling and platform compliance alongside the practical marketing work.

Google Maps Compared With Apple Maps and Waze

Choosing between navigation platforms comes down to what you actually do with one. The three main options differ most on transit accuracy, business data and privacy handling.

For a business, the comparison is less relevant than it looks. Google Maps carries the largest share of local discovery, so it is the priority, but Apple Maps listings are worth claiming too given how many iPhone users default to them.

How ProfileTree Helps Businesses Get More from Google Maps

Knowing what Google Maps is and making it work commercially are separate problems. ProfileTree helps businesses across Northern Ireland, Ireland and the UK turn local search visibility into actual enquiries, covering Business Profile optimisation, local search strategy, review management, and the social media marketing that amplifies the same trust signals elsewhere.

Business Profiles support video as well as photographs, and a short, well-produced clip does more for confidence than another stock interior shot. ProfileTree’s video marketing work is used by clients across the region for exactly this: brief films that answer the question a customer has before they walk through the door.

Since 2011 the team has completed over 1,000 web projects and supports businesses from initial build through to ongoing search, content and AI work.

The Bottom Line

Google Maps is a live geospatial platform rather than a map, and for local businesses it is now a primary discovery channel that feeds Google’s own results and the AI assistants people increasingly ask instead. Getting it right is not complicated. It needs accurate detail, real photographs, current information and consistent attention.
